How Much Difference Would A 4.8kg Bike Make At The Tour de France? | GCN Tech Show Ep. 82


– Welcome to the GCN Tech Show. This week, we’ve got new bikes, a new turbo, new tires, the
bike vault, your upgrades, plus our main talking
point, how much difference would a super light bike
make at the Tour de France? (upbeat music) How much difference
would a super light bike make at the Tour de France? What if the UCI bike weight limit of 6.8 kilograms was abolished, and riders were allowed to use the lightest bits and pieces
available to humanity? How much faster would
they go up the climbs? Well, I decided to do some math. To see what the effect
of a four and a half kilogram hiker bike would be, over a, well, 6.8 kilogram UCI legal bike. For the sake of the
argument I’m going to look at some of the Thibaut
Pinot’s efforts that he’s done in the tour because, well,
he’s been the strongest climber in the race at
this point when we record this show, probably
given him the curse now. So first up, we’re going
to look at his efforts from stage 15 of the
tour on the Prat d’Albis. He did the fastest time
at the Summit finish. And if we have a look at it,
it’s a 10.2 kilometer climb with an average gradient of 7%. And according to Strava, he did it in 27 minutes and six seconds, which is, seriously rapid. And then what we’re going
to do is plug that data into a bike calculator,
that’s really available on the internet, with all the details. Now, Pinot’s weight is
said to be 63 kilograms. He’s a light dude! But, we’re assuming he’s not riding naked so we’ll add on an extra
kilogram for his clothes. But, we’re giving him clothes. And then we’re also going to put his bike weight at 7 kilograms. The reason for this, rather than 6.8 is, well it has bottles on it and a computer. Which kind of knocks the
weight up a little bit. Now, if we put in the
details of the climb, we can see that this
calculates Pinot’s power to do that time is 396 watts. Which is seriously, seriously impressive! But also, roughly what
you’d expect for someone who’s able to, well, potentially
win the Tour de France. Now, if we drop Pinot’s bike weight down to the four and a half
kilogram hiker bike weight, then hypothetically, all
of the things being equal Pinot could’ve gone up in
49:56, over a minute faster then on the 7 kilogram bike set up, which, seems like a lot to me. Especially, if he’s trying to compete for the win in the grand tour. So, I’m going to look
at something else now, which I think is quite interesting, which is, what if we look at just the difference between
a lightweight climbing bike, and an arrow bike? A lot of the top world tour climbers, they don’t go for the arrow bike, ’cause it’s usually slightly
heavier, 400 grams or so. Not much, but slightly heavier. Let’s see what penalty that would have on a
climb like the Tourmalet. I got this idea because I looked at both of Valverde’s bikes on the tour. He had his ultimate and
he had his Canyon Aeroad. Now, he prefers the ultimate
because it’s lighter and he can get it on the
UCI limit of 6.8 kilograms. I weighed his Aeroad as well, and that came out at 7.15 kilograms. So, ever so slightly heavier,
just, well, 350 grams. Not much. So for the sake of the argument here, without 400 grams onto
Thibaut Pinot’s bike. And, well, when you plug those numbers in, it makes him 12 seconds
slower, on the Tourmalet. Just 12 seconds. 12 seconds isn’t a lot. And it’s also not taking into account anytime that he could
potentially claw back out of that 12 seconds through riding a more aeroad dynamic bike. Now, the speeds that Pinot
rides up the climbs which is, well, over 20 kilometers an
hour, there’s a good chance that there’s some significant
Aeroad savings made, but, I haven’t done the
math to work those out. Now, what this kind of
suggests to me, is, well… And I’m surprised by
these numbers as well, is that maybe we care a
bit too much about weight. But this is all estimates, and if there’s any of you watching at home you have a more sophisticated
mathematical models, or ways of calculating. If then, please, by
all means, get in touch or write in the comment
section down below. But we want to know
what you think as ever. So, get involved in the
comment section down below. Do you think the pros
should be allowed to ride super light ridiculous bikes? Do you think we care too much about weight (dramatic music) Hot Tech now, and we’ve got
blooming loads this week. First up, bikes. And this, from Colnago, which is the V3RS. Brand new bike, and supersedes the V2R which you may have seen Dan
Martin riding this year. And, in the Tour de France. It’s available in both
rim break, and disc break. And, it comes in as an
impressive 790 grams for a disc brake bike. Albeit, in a size 50. Now, it can accommodate
28 millimeter tires, and it said to be even stiffer. 12% in the rear, 6% stiffer in the front. And, like every other
performance road bike that’s come out so far this
year, is lightweight and aero. So, you’ve got aero tube shapes on the down tube, the head tube. You’ve got dropped seats
days, integrated cables. Yeah. It’s another one. And, also out this week, was
the new Cannondale CAAD13. And again, it’s another
performance road bike. It’s got aeroad.(laughing) So it’s basically the aluminium version of the new SuperSix EVO. And replaces the Cannondale CAAD12 which had its classic shape. So once again, dropped seats
stays, aerodynamic tube shapes, and more integration of the cabling. Interestingly, though, Cannondale, well, they haven’t called it the CAAD14. When the CAAD12 came out,
that replaced the CAAD10. And I went to the launch, and at the time, they said it was the CAAD12 and had missed the CAAD11
because they believed it wasn’t just one
better, it was two better. So, presumably, the CAAD13
is, well, only one better than the CAAD12, but, better nonetheless. And also out this week, there’s
a new bike from Cervélo. Right, this is getting ridiculous! Look at that. Yes, it’s got aero as well. It’s got aero tube shapes integrated cabling and dropped seat stays. But this one is a gravel bike. It’s designed to be a gravel bike for those that want to go fast on gravel. A bit like the 3T Exploro. So, you’ve got those aero features there, and it’s less focused on those “you want to kind of just
go on gravel” adventures and “cover up their bike in loads of bike packing luggage.” But, I have to admit, it
does look rather cool. And it can take 650B wheels as well. Our mates at Elite have
launched a new smart trainer. It’s called the Suito and it comes ready to go out of the box. Including with an 11 speed cassette. So, you’re ready to go on
any online platform you want, such as Zwift, being a smart trainer. And according to Elite, it
has an integrated powering, so which is 2.5% accurate. It’s capable of simulating
gradients up to 15%, and, has a max wattage of 1900 watts. Which, well, essentially
makes it opine proof. Top tire tech now,
Continental has just released a new, limited edition, 200
thread per inch version, of its competition tubular tire. Now according to Continental, the new tire is 10 watts faster
of 40 kilometers an hour. And, it has a specially yellow
Tour de France stamp on it because it’s, well, special,
and limited edition. And there’s another Tour de France twist. There’s only 3480 of them being made. Which, top marks if you
guess this correctly, is because that happens to be the total number of
kilometers in this year’s Tour de France. Cool. British wheel brand Hunt
have released a new set of alloy disc brake wheels. The 34 Aero Wides. And they’re making quite
a big claim that these are the fastest aero tested
alloy disc brake wheels. And they’ve done this by
fitting 25 millimeters tires to the wheels, and then testing
them against competitor’s wheels, using the MAVIC Wind
Average Drag Calculation, to find the results. Now as the name suggests, these wheels are 34 millimeters deep,
with a 26 millimeter wide external rim. But it’s really cool to see
a relatively small brand, pushing the R&D. Hot flashy sunglasses tech now. 100% the sponsors of
Peter Sagan have launched a very limited edition pair of shades. Limited to just 50 pieces. They’re called The 100%
Speed Trap Sagan 2019 LE’S. Catchy. And, they feature a gold
coated lens, 24 karat gold. And there’s etching on them as well. And, you also get a signed
card by Sagan himself if you’re lucky to get a pair. But, there’s only 50
pairs, two of them have already been auctioned off for charity, and the other 48, well, I can’t
see them for sale anywhere. I’ve also not seen John
for a couple of days. (screw sound) It’s now time for screw
riding upgrades, buy upgrades. Where you submit evidence of the upgrades that you’ve made to
your bikes, or equipment for the chance to win the ultimate prize. The Camelbak Eddy Water Bottle. GCN themed. Don’t have one here
right now, but trust me, we do have plenty of them to give away. Now, last week, was a battle
between Eric, and Barney. Yes, it was Eric and Barney. Now, the winner with 75% of the vote was Eric. (crowd cheers) Yes, it was, it was Eric. (laughter) This week, we’ve got Federico Buenos Aires in Argentina. This is Federico’s first road bike. It came about, thanks
to traveling in Europe when he was staying in Israel. Now Federico realized he couldn’t live without his bike, so he popped along to a local bike shop,
and in the dark corner, darker than you can imagine,
was a Pinarello from 1997. One of the rims was starting
to crack around the eyelets, and Federico thought
that some small upgrades would make it into the
bike he would cherish on his return to Argentina. Changes were made. He swapped out the cam
pack Falacci rear mech to the carbon bodied record. And he also changed the bars
in STEM to modern oversize pro PLT versions, and he
wrapped them in, well, the rather delicious super Cass bar tape. Now, he finally replaced the cracked rim and got a pair of Campagnolo Berlin rims. Very lucky, as there can’t be many of those pairs still around. Anyway, there it is to begin with. I’m looking forward to this. Okay well that’s… Whoa, oh, nice! I like that you’ve kept the original paint job there as well. And, you’ve swapped the STEM. Nice. That looks a lot better. That’s made a big difference. With that bar tape,
you’ve done a great job of matching that to the paint
job on the original frame. Nice details. I think you’ve done an
excellent job there. But I am slightly worried Federico that you have two heads. As you have two helmets propping up the bike in that picture. Federico, is facing stiff
competition this week, he’s up against Judson From the picker UN’s Roundhouse, Canada. Now, Judson and his wife were
looking for a winter project to spend the long Canadian
winter on together. And they picked up this
dilapidated late 1978 Peugeot PR series road bike. Upgrade segment, lot of Peugeots, they get a lot of love, I like it. Now, Judson’s wife did all of the creative and artistic work, which
included sand blasting the frame down to his bare steel, and making their own version of Peugeot’s famous tulip red paint. And recreating the logos
with a vinyl printer. That’s impressive. I’m really impressed with that. Judson cold set the frame
to give enough rear drop out spacing to put in a
modern set of Mavic wheels with 11 speed spacing, and it was built up
with mostly Shimano 105, and Richie classic saddle. And finished off with some gorgeous hand walled Michelin dynamic classics. Nice. Gives it a good look to that. It totally works. And the matched bar tape with the saddle (clicks tongue). Got a lot of time for that Judson. Top job and Judson’s wife too. Sorry, I don’t know your name. But, it’s not up to me, so
let us know what you think, and you can vote up here. Judson vs. Federico. (dramatic music) Time now for my favorite part
of the show, the bike vault. Where you submit pictures of your bikes, and then myself and, (wind blows) myself, will judge them, to be nice, or super nice. Now if they’re deemed
to be super nice then, (wind blows) I’ll ring the bell, and
they’ll go in the bike vault. So, I’ll get the bell. There it is, right. First up this week, we’ve
got Tomas, who or Thomas. Who’s from Mary The Virgin
church East Haden, in the UK. I don’t think he’s from there, I just think that’s where his bike is. It’s a B-TWIN Ultra 900 CF. Check that out, great. I mean he’s got it in yes
Biggie Smalls in there. Like the way that the bar tape matches the saddle, color coordinated. And he’s got matching bottles in there. Very tidy in his elite Vico cages. It’s good, it’s very good. It’s nice, but there’s a
little bit of steerer tube above the stem, so I think
that one’s just a nice. Okay, right, next. Duncan,
who’s from Portland, in Oregon. Now, Duncan has his BMC 021. Check this out. Look at that, That, is very very tidy indeed. I like his absolute black chain rings. Biggie Smalls again, and,
he’s prepped it for the shoot. I like that light he’s got that as well. And he’s very nicely matched up the wheels and got the valve stems
perfectly down below. No excess steer achievement. It’s nice. Yeah, your lawn needs a mow. Nice, right. Next up is, who’ve we got next? Chris from Palisades, New Jersey. In the US of A. He’s got his 2004 Trek 590SL. Project One Bike, an
earlier project one bike, very cool indeed. Chris, nice name sticker, you’ve
got there on the top tube. I like that. You’ve kind of, nice old school. That’s a very good name, I’ve seen you’ve taken care of that, it’s been your pride & joy. Though I have to say, It’s a fine example of
an earlier carbon bike. The red bar tape, is,
yeah it’s kind of clashing a bit for me though, it’s a nice. It’s a nice, yeah. Next up we’ve got Prince
Sevo from Malaysia, and I’m sorry if I completely
massacred your name there. Probably I pronounced it correctly. But, we’ve got your Willier GTRT. This is a great, great photograph. Love it. What an amazing view that is. I really want to go to
Malaysia, that looks incredible. And that’s a really nice bike. Really nice really nice. Biggie Smalls once again, I hope you’ve not got a crank in the three o’clock position, but I’ll forgive it ’cause I can see you’re using your helmet
to prop up the bike. Although, it’s a beautiful bike,
beautifully composed image, great everything’s just… But what’s wrong with it? I quite can’t spot something
that’s wrong with it. Uh, the wheels aren’t quite
aligned with it, sorry. The wheels aren’t quite aligned, sorry. Next up, finally, we’ve got Tommy, from the Navel Air Station in Fallon. Now, what a lovely sunset
photo Tommy has taken in the United States Navy’s
Premier air-to-air air-to-ground training facility and home to the navel fighter weapons school. AKA top gun. New Token Trailer arches were pretty cool. But would you look at that,
it appears to be a V897 A7 Corsair two on the left there. A carrier there capable subsonic light attack air craft. The first saw active
service in the Vietnam war. But the tech stats are
what we’re here for. So top speed 690 miles per hour at sea level, but a 500 feet fully loaded with 12 NK, you’ve got MOCK 82 bombs. The speed dips to 647 miles per hour, but speedy none the less. Also fitted with just
one gun, but water gun. The impressive M-61 A1 volt
and 20 millimeter rotary cannon has over a thousand
rounds of ammunition. Nice. Now the take off distance
for that particular air frame was also 520 meters but fully loaded and over 19,000 kilograms, nice. Very nice indeed. But unfortunately not a super nice. So yeah that’s the end of
the bike vault this week. More bike vault next week. Its nearly time for the end of the show. I know. But don’t worry I’m going to read out some of your comments
first, from last week. So first up, Cerebellum, who wrote, “Jon’s crooked glasses
are driving me crazy.” I assume he means not like
the fine young cannibals but, in another way. Anyway that’s why he’s
not here, you guessed it. He’s not allowed to come back
until he’s rectified that. – Oh yes. – Won’t happen again. Jeremiah Sullivan says, ” Thanks a lot. I laughed so hard during “Buy Upgrades” that I woke the baby on me that I had just worked
very hard to get to sleep.” Sorry Jeremiah, I hope this weeks show doesn’t make you laugh. (laughs) Nick Coulter says, “Not
sure if it’s just the tan, “but Jon is looking
properly healthy here,” “aside from the voice, “what you been eatin’, mate?” I’m not sure what he’s been
eating to be quite honest. I’ll try and find out for you. (laughs) He’s been drinking quite a lot. (laughs) And Eloi Chayer asks how has Jon, oh it says, “Jon has become “the Godfather of the cycling world.” – True story. (laughs) – Okay, right. Well like and subscribe
here if you haven’t already, and if of course, you enjoyed the video. And if you’d like to get your hands on one of these awesome GCN themed shirts. This is the GCN outdoors, there’s one with dutch corner on it. Well, there available in the GCN shop. So you can head over there
and help support the channel. All right. See ya later. Bye.

  1. Was Ollie being too harsh in the bike vault this week?

  2. i think the limit should be dropped to 5kg

  3. Yep.. you cursed Pinot good and proper!

  4. Geordie Ollie let his true voice out here…..Gan on me Sunna!

  5. And cursed he was Ollie. Pinot is out ☹️

  6. I think you owe Pinot a pretty serious apology given todays stage.

  7. YOU GAVE PINOT THE CURSE!!!!

  8. Well looks like you did indeed curse Pinot

  9. The curse has hit again.

  10. "Probably gave him the curse now….."

  11. The GCN curse strikes again!

  12. Can't believe you cursed Pinot…………….saddest moment of the entire Tour….THANKS A LOT OLLIE

  13. Ouch, jinxed him, well done lad!

  14. Definitely gave him the curse !

  15. The GCN Curse takes out Thibaut!

  16. You cursed Pinot….he left the tour……

  17. Wait a minute… you DID put the curse on Pinot! :O

  18. Did you say ‘Penos Power’?

  19. you've uhh.. you've definitely cursed Thibaut Pinot

  20. Maybe you should stop mentioning riders when there is a race going on. Or just stop mentioning riders. Period. GCN is bad luck

  21. The post production is almost as funny as the presenters. Good episode, taking the piss on the nice/ super nice.

  22. The curse was real…. Jeeze you took him out of the race completely shame GCN shame.

  23. after stage 19, bernal leads alaphilippe by 0:48 … 1 minute saving on one climb is massive … the weight rule though should be applied based on the rider's weight since it's crazy that egan bernal (60kg) and peter sagan (73kg) have the same weight bike …

  24. You cursed Pinot!!!

  25. Ouch Ollie…

    Not just cursed, but tore his VMO…

    I think the GCN curse is getting stronger…

  26. Bike vault has been taken to a new level

  27. Ollie back at least stage 15/16 day "Pinot is the best climber right now, at least as of recording. I've probably cursed him"

    Stage 18 GCN releases video
    Stage 19 Pinot abandons

    Who is next on the GCN curse list?

  28. I'm a bit concerned about the placement of the levers on the Peugeot.

  29. No excess steerer tube on the BMC because it's the opposite of slammed.

  30. Dr. Ollie that was hilarious many thanks. Well done on the bike vault, and YES you did curse Thibeau P. (1:01) WTH ?!

  31. Jeez…..that 'Crack-and-fail' is SOOOOO ugly!

  32. Wow Ollie you really did curse Pinot 😬

  33. You cursed Pinot

  34. Ollie, please just leave.

  35. Abolish the weight limit for the bike and introduce a safety certificate for each model, similar to cars. This would keep up safety standards but allow the bikes to get lighter.

  36. You cursed Pinot OMG :O

  37. Let's better increase the limits to 13 kilograms, if the riders are stronger than any of you twice, then let the bike will be twice as heavy. This will equalize their performance with the rest of the non-pro world, but in terms of rivalry, weight does not matter much.

  38. Re the hot topic of bike weight restriction in the TDF, the podium is about the athlete hence the playing field needs to reflect that, ie no advantage from equipment (or any other means) for that matter. By the way, is the same bike weight restriction applicable to time trial bikes ?

  39. Why don't the teams make the aero bikes 6,8kg, should be very easy with s few lightweight components!?

  40. The pros have a sustainable power around 6w/kg. So reducing bike weight by 2kg down from the legal 6.8kg would imply a saving of up to 12 watts if aerodynamics remain the same and the slope is significant enough (around 8-10% for pro riders and less for amateurs because of the lower speed)

  41. Kinda feel like GCN is scraping the bottom of the barrel now 🙁 Used to be awesome when Matt, Dan, Si and Tom were the mix. Now we've got endless remakes of videos, Ollie's cringeworthy, racist, stereotyped accents – and the 'Bike' Vault, where people send in photos of their bikes only to have the presenters talk about everything else in the picture BUT the bike. It is with great sadness that I'm unsubbing.

  42. Ollie cracks me up

  43. Pinarello was nice, I almost bought a similar one but I did not in the end because it was aluminium not steel

  44. Pros should ride the most high tech, ultimate bikes!

  45. You cursed Pinot 😩

  46. Just for the sake of letting technology advance, lift the UCI rules. Companies aren’t going to release a 200g frame that snaps in half if someone pedals too hard, think of the marketing there, bad for business, bad for safety, won’t happen. Lifting the aero rules would be more impressive though to see how that pans out.

  47. 12 seconds is a lot if you're trying to win the tour

  48. Periodic Table – Aluminium = 13. Enough said…. lol

  49. What is on your front tooth?

  50. HELP!! What can I do to help in headwinds? You know the ones where you have to pedal down descents! I seem to struggle mentally in them and end up blowing really quickly. Any tips to get through them would be awesome. #askgcnanything #torqueback #gcnshow

  51. How can you possibly say that "we worry too much about weight" when 2kg can make over a MINUTE's difference on a 20min climb?? That's *completely** game changing. Obviously if the UCI limit was reduced the aero bike would be lighter too, so I don't know what that latter comparison was all about.. The current ridiculous UCI limit basically penalises lighter riders very significantly – it should be reduced substantially to keep pace with technology. But of course it won't be, because of the mindless marketing of pointless disc brakes and the need to keep porky disc brake bikes competitive so that the manufacturers can continue to try to sell them.

  52. Ollie was definitely not being too harsh in the bike vault! As well, his sarcasm about the new bike designs all being the same is not only thick – but justified too! How about a segment dedicated to why all these manufacturers are copy-cats these days? And is there anything coming from just around the corner that might change this trend?

  53. Much of the aerodynamic advantage of the aero bike would be negated by following wheels.

  54. #AskGCNTech Hi, I'm 63, I love GCN and have had caliper brakes all my life. I was wondering if hydraulic brake actuators are necessary? Does one really need the hydraulic fluid in the brake lines and the calipers? There are systems out there with hydraulic fluid in just in the calipers and they use cable actuators. A simpler system seems like a better idea.
    Based on industry trends I know that my next bike will probably have disc brakes. I was wondering why the cable disc brake systems are not as popular.
    Cheers
    Mark

  55. Oooooo big Time gcn curse, Ollie you gotta let the bookies know as soon as you say it

  56. What the flick are Biggie Smalls?

  57. A lower weight limit would make for more interesting tactics, but I'm not sure that would make pro cycling more interesting.

  58. If one team had 4.5 kg bikes wouldn’t they all have them?
    Thus negating any gains ?

  59. Good stuff Ollie.. I think the first argument that the top climbers prefer a lighter bike despite the small differences in weight from their team Aero options, is due to the psychological advantage. It's the psychological challenge of riding quickly up hill that IMHO also makes the difference between good climbers and the greats. So if there is a perceived advantage to a lighter bike, top climbers will use it. And.. If the UCI relaxed regs for weight, you can bet the super lightweight bikes would be in the peloton in no time.

  60. do we care too much about aero and not enough about BMI?

  61. Did Conti reduce the number of their limited edition tyres to reflect the reduced stages, I wonder?

  62. That BMC deserved a super nice!

  63. The extra weight matters more during accelerations, and if the key moment is being able to accelerate away from the GC group at the steepest section on the final climb, then the lightweight bike will be the better choice. I still ride my Madone SLR more than my Emonda SLR though.

  64. So is Continental going to reduce the production run of those tires to reflect the stage shortening in this year's tour? Or are those last 200 or so tires going to be produced in some special color, to remind us of the craziness?

  65. Surely we care a bit too much about Aero… if the difference is 12 seconds, the aero gains are likely less than that, plus the entire rest of the stage when he is sitting behind 5-150 other people the aero advantage of an aero frame is even smaller. Doesn't this suggest that for an uphill finish a light bike is going to be better? 8-12 seconds gain at the top of a climb will usually give someone a bigger GC gain that a few second on a comparatively flat stage / flat finish were you'll be more likely to have at least a few other riders around you reducing the aero advantages of an aero frame.

    But who knows. 🙂

  66. Since when was Israel in Europe??

  67. dhrthrhhrjhn…. Tried the Olly finger shake at the keyboard. Didn't work.

  68. Someone was enjoying an energy bar a little too much!!

  69. a) Flo cycling did make some serious analysis on this and they came out to say: Aero trumps weight. Having said that, they do sell aerodynamic wheels, but they're triathletes themselves.
    b) Yes. Go as light as you want and sell us the friggin parts! We've got rider or system weight limits on some parts anyway and putting weight on a superlight bike to get it up to the UCI limit helps noone. I understand that this may make it hard for someone to advance from amateur to pro level, but club races often have more relaxed rules anyway, so what the hell. We're not talking about giant gains and pro teams have good enough tools to assess rider quality.

  70. Nah 6.8 kg is a nice arbitrary weight.
    However, we can conclude that, over the course of the 1989 Tour, Fignon’s Deltas cost him more than eight seconds.

  71. This misses the most important point: it would help lighter riders more than heavier riders. The UCI rule penalizes light riders.

  72. What dos biggie smalls mean.

  73. Olly – soo stiff on the bikes !

  74. Thanks God UCI are still keeping minimal weigth limit. We already saw how team Sky member broken brittle trispoke crabon wheel and crashed his TT bike just by hitting simple pothole hardly seen by naked eye. Safety is way more important thad stupid few seconds you could gain. Not even talking about longevity of such 4.5 kg bike, although pro teams could dump those 5k+ frames after each stage and use a new one.

  75. Time saving for climb aero v light weight bike repeated every day of the tour is easily a winning margin!!!!!!!! weight limit – competition re weight will filter down in new tech for all of us so do it but to improve racing use one design. Now it seems we are between 2 stools (in the nicest possible way of course).

  76. You forget stiffness, that you have to descend as well… etc. Lightness is not the solution.

  77. 1:00 yup. Yup, you did.

  78. Without a weight limit, well-funded teams can spend as much money as they want on super light materials and receive insanely expensive components from their sponsors. Meanwhile, less-funded teams with smaller sponsors could be at a huge mechanical disadvantage, even if the rider is better.

  79. love the typing fingers!

  80. That Peguet was good, until I saw the angle of the shifters

  81. That BMC needs more saddle to bar drop… Jesus

  82. Yes, I think riders should be allowed to ride light weight bikes. It will be interesting to see how much fast the times at the tour would be.

  83. Your lawn needs a mow! ahahahhaahahaha

  84. ok. 20 sec is very important but… You should remeber that if smth is going up hill it must go down hill and than lighter dosn't mean faster. how it counts for the total time up and down? 😎💪🔋🚴

  85. Is my Bike good? https://ibb.co/sVVwNtM
    (Website includes Kufr)

  86. Love your impressions, keep up the good work.

  87. Ollie you SHOUD NOT be judging the bike vault. Bring John back. Sorry mate.

  88. doesn't seem fair that the min bike weight is the same regardless of the height/weight of the rider

  89. I thought I may be an old man before you…didn’t bother… to find a bike to ring that damn bell

  90. I want the pros to ride lighter bikes just so that rim brakes get some more attention and bike companies make some lighter models. It's a shame that brands like cannondale and specialized have discs on all their top tier bikes. A top tier tarmac is both heavier and pricier than my mid level emonda!

  91. In my experience, the increase in speed uphill with a light road bike vs a much heavier touring bike is completely in line with mathematical prediction.

  92. Valverde prefers the Ultimate because it doesn't have shitty boat anchor disc brakes that also mean a disadvantage aero wise too.

  93. hahaha bike vault parody accents are best.

  94. Actually, a while back (in the 80's), someone calculated that aerodynamic bikes started to make a difference at 25 mph & up. So climbing on an aero bike, if there are no descent afterwards, is useless and you are just getting more tired by bringing the useless extra weight up the hill. Therefore, on a stage race where you want to be the freshest as possible every morning, racers tend to prefer lighter bikes whenever possible.
